The rolling settlement ensures that each day's trade is settled by keeping a fixed gap of a specified number of working days between a trade and its settlement. At present, this gap is five working days after the trading day. The waiting period is uniform for all trades. When does one deliver the shares and pay the money to broker?As a seller, in order to ensure smooth settlement you should deliver the shares to your broker immediately after getting the contract note for sale but in any case before the pay-in day. Simliarly, as a buyer, one should pay immediately on the receipt of the contract note for purchase but in any case before the pay-in day.
